Abstract

PURPOSE: To avoid the inefficiency in utilizing sensible heat only of a heat accumulating material intended for utilization of latent heat on the outlet side where temperature rise is small and thereby to enhance heat accumulating efficiency by a method wherein a bed packed with a heat accumulating material intended for utilization of sensible heat is provided on the side of the outlet for a heating medium in a heat storing period.
CONSTITUTION: When introduced from an opening portion 17 during heat storing period, a heating medium comes in to contact with a packed bed 15 of a heat accumulating material intended for utilization of latent heat and with a packed bed 16 of a heat accumulating material intended for utilization of sensible heat. At locations from O to M shown in the figure, there takes place an absorption of latent heat attended with the phase transition of the packed bed 15 to liquid state, and at locations from M to L where temperature rise is small, an absorption of sensible heat by the packed bed 16 occurs. On the other hand, during heat releasing period, the heating medium is introduced from an opening portion 18, preheated by the packed bed 16, then contacts the packed bed 15 to receive the latent heat released by the phase transition of the packed bed to solid state, and flows out via the opening portion 17. Accordingly, heat accumulating efficiency is enhanced because the packed bed at locations from M to L of the heat accumulator is composed of a heat accumulating material intended for utilization of sensible heat without attendance of any phase transition during heat accumulating and releasing periods.
